Girl In School Uniform Outfit

In Scotland, some local councils (that have responsibility for delivering state education) do not insist on students wearing a uniform as a precondition to attending and taking part in curricular activities.
Turkey abolished mandatory uniforms in 2010.
In the United States, a few states have regulations declaring that public schools must allow students to drop out of uniform policies. Although Section 83 of the Massachusetts Legislature appears to prohibit dress codes in public schools by declaring that schools may not "abridge the rights of students as to personal dress and appearance", Section 86 states that "The provisions of sections eighty-three to eighty-five, inclusive, shall apply only to cities and towns which accept the same" and other sections of the law allow schools to impose dress codes, and in fact many public schools in Massachusetts (mostly in the Boston area) have mandatory school uniforms.
In 1969, the United States Supreme Court ruling in Tinker v. Des Moines Independent Community School District affirmed students' rights to free expression in public schools, although this related to the wearing of a black armband (not to uniforms as such). California Education Code 48907 affirms students' rights to "the wearing of buttons, badges, and other insignia" as well freedom of speech in student publications, subject to limited restrictions.
